LOUIS C. VANDEELIP, OF ELKHART, INDIANA.

PNEUMATIC CONVEYER.

Application led July 27,. 1916, Serial No. 111,573.

To @ZZ whom z' may concern Be it known that I, Louis C. VANDERLIP, acitizen of the United States, residing at4 Elkhart, county of Elkhart,State of Indiana, have invented new and useful lmprovements in PneumaticConveyers, of which the following is a specification.

This invention relates to pneumatic conveyers wherein fluid underpressure, such as steam or compressed air, is introduced to a pipeconduit interior to kconvey loose and disintegrated materials such asashes, sand, gravel, and the like.

An object of my invention is the production of an improved device of theclass described which may be connected at both ends with straight pipingfor a conduit line for straight away conveyor work, thereby eliminatingelbows, bends, etc., from the conveyer line. Another object of myinvention is the provision of improved means for the introduction offluid under pressure axially of a straight conveyer line, whether inahorizontal, perpendicular or inclined position. And another object isthe production of aV chambered fluid pressurenozzle carrier in which thefluid pressure chamber -is flattened, or elongated, to reducethetransverse displacement of the nozzle carrier within the conveyerline. And still another object is the provision of means for protectingthe nozzle carrier against wear due to the abrasive action of thematerials conveyed. And a still further object of my invention is theenlargement, or bulging, of the main casing thereof j adjacent thenozzle carrier to facilitate the movement of the materials past thenozzle carrier.

(.)ther objects will be mentioned and described from time to timeherein.

The preferred embodiment of my invention is clearly shown on theaccompanying drawings in which, Figure l is a longitudinal section inelevation; Fig. 2 is a section on the line 2--2 of Fig. l; Fig. 3 is asection on the line 3--3 of Fig. l; and FiOf. l is a sec'- tion on theline Li-4 of Fig. l. bimilar numerals of reference refer to similarmembers and parts of members throughout the Vseveral views on thedrawings.V

Referring to the drawings in detail, the numeral l indicates a channeledbody member provided with suction intake opening 2 and an outlet opening3 at the opposite end and preferably in axial Y alinement, and adaptedto be introduced in a pipe conveyer line intermediate its extremities,or to have Specification of Letters Patent.

a suction pipe fastened to intake opening 2 anda discharge pipe toopening 3. The numeral el indicates an opening formed in the wall of themember l to permit of the introduction of the nozzle carrier 5 providedwith the projection 6 arranged within the interior of the member l, andwhich is provided also with the steam chamber 7 which is flattened, orelongated, to minimize the f transverse displacement of the carrier 5`and the projection within the pipe member l. The chamber 7 is alsoenlarged somewhat in area, in the direction of the elongation, toprovide ample steam supply and the maximum pressure thereof at the steamnozzle hereinafter described. The upper end of the steam chamber 7 isprovided with an inlet opening 8 which is in communication with a steamsupply pipe 9 leading to any suitable source of steam. By elongating thesteam chamber 7 and making the side walls thereof` of reasonablethickness the projection 6 displaces the minimum space transversely ofthe member l, thereby facilitating the movement of the conveyer contentspast and around the projection G. The numerals l0 and il indicateflanges of the nozzle carrier '5 adapted to be fastened to the base l2,of member l, by bolts 13, 13, the flanges being suitably apertured `forthat purpose. The numeral 14 indicates an aperture formed in theprojection 6 adjacent its lower end and adapted to receive and rigidlycarry the steam nozzle l5 which is preferably placed in axial alinementwith the opening 3 of member l, and which is adaptedto introduce thefluid under pressure to the conveyor pipe interior toY create thenecessary suction for the movement of the materials therethrough.V Thenozzle l5 may be fastened to the projection G in registration with theaperture 14 in any suitablemanner, but the preferred method is by bolts,screws, or screw threads on that portion thereof within the opening 14.ing end of said nozzle l5 rigidly held in substantially axial alinementwith the discharge opening 3 of the member l the wear on theV Theprojection 6 of the nozzle carrier 5 is,

provided with an inclined, or slanting, wall G to which is detachablyfastened the inclined wear plate 16, the latter being held in .By havingthe Vissubody member projecting into llying the lower end A memberremovably position by a bolt, or screw, 17 engaging the iiange 10. Thewear plate 16 is provided Vwith a forward extension portion 18 underofthe projection 6 tov protect the latter against abrasive action of theconveyer contents. The inclined wear plate 16 isl provided with apointed end by beveling the surface thereof as at 18', 18, as indicatedin Fig. et, to deflect the moving materials and to offer theminimumamount of resistance to the passage thereof. Being detachablethewea'r plate '16 may be removed and another substituted therefor whenworn out. `To further facilitate thematerials past and around theprojection @where coarse ashes and heavy clinlrers are being handled bythe conveyor, the bottom and side walls of the body member are bulgedoutward at 19 and Q0, respectively, adjacent the projection 6, therebyincreasing the cross-section area thereof.

A suitable hand hole may be made in the member at any desirable locationeither for inspection thereof or for the introduction of tools to theinterior thereof for any purpose. Y
